... Last time I checked, it'd cost about the same as the Garmin GPS 18. If there's enough interest, I might carry it. It's really just a matter of how much...

... Yea! Check out the National Geographic Topo module and you might see a name you know there... GPSBabel is a good utility, very useful for converting...
From experience with Deluo I can only say, they are often the cheapest source, and that's something to remember. Sometimes they switch vendors as different GPS...
I've looked into importing GPS receivers myself, but most would cost more than the Deluo units, even before shipping and duties. Unless I wanted to buy 10,000...
I already expect the answer to be "no", but I promised a friend (who didn't check with me before he purchased) I'd ask... The friend bought the "Deluo USB GPS...
Good question. I was under the impression that they were native USB, but it's certainly possible that the converter is in the cable. I'll have to check with...
12 MHz roughly. I think the transmitter frequency is supposed to be 12 times the crystal frequency. For mine, I used 12.288 MHz. Should be 32pF load...

Yes. It's a godawful piece of engineering. Set it up to run on 145.800 and you'll put out a nice big spike at 121.5 and probably get a visit from your local...
A German version of the OT1x manual is now available at http://n1vg.net/opentracker/ot1x_Benutzerhandbuch.pdf. Many thanks to Manfred Mauler, OE7AAI, for the...
Is that the schematic for the TinyTX I have seen referenced? Does anyone have a really "Good" transceiver schematic, or a good kit? PiperPilot ... 145.800 and...
No, it's an adaptation of the Ramsey MR6 model rocket transmitter kit. I redrew the schematic, substituted some modern parts, and did a new board layout. Of...
Scott, I wouldn't even use it for rocket tracking the way it's designed..... On another note: our TX's are ready for first run of 10pcs pre-production but I'm...
Yeah, it's frustrating but I have to agree - the Chinese companies I've dealt with have almost always been more willing to actually do business, even when it's...
Juergen, Are you creating a Transmitter for APRS use? I'm fairly new to the group here and thats exactly what I am looking for. Something smaller and less...
Curtis, short answer: yes. Long answer: it's a 2.5kHz synthesized TX with at least 85dBc spurious suppression in 2.5kHz mode (better for 10 and 12.5kHz). Can...
I didn't see any further reply to this but I encountered "similar confusion" when doing my research. It "appears" that Deluo has a "USB Only" version AS WELL...
Hello, I wonder of someone might be able to point me in the right direction...This is a brand new mode for me and I'm not 100% sure I'm set up right, but I'm...
What I sell is indeed the Universal GPS WAAS. All of the 'universal' ones are, as far as I know, serial. They sell a nice inline serial-to-USB converter (I...
It's hard to know what's going on without at least a scanner to listen to. You need to make sure that audio is actually being transmitted. Your config looks...

Good advice. Shorter packets are always better - don't enable options you don't need. The shorter the packet is, the less likely it is to be corrupted by...
Scott, What is the current status of the OpenTracker (OT1) firmware source on SourceForge--is everything up to date? I would like to get the latest source...
Thanks for the suggestions guys. It's working great now - the problem was the audio level being set too high. I was able to listen to it on a DF receiver we...
